Gav: What the hell are you?
Figment of Gav's Imagination: You passed out! This is a dream sequence of sorts

Gav: Yes, that would explain the anvil and dancing beer
Figment of Gav's Imagination: It also means you can do anything you want! No consequences! No repercussions!

[[The dancing beer slips and spills itself]]

Gav: First, it looks like I need another beer.
Figment of Gav's Imagination: Speaking as a figment of it, I apall your lack of imagination.
